MANGLE.

SPECIFICATION forming part of Letters Patent No. 760,530, dated May 24, 1904.

Application filedSeptember 22, 1903. Serial No. 174,150. (No model.) I

To all whom 'i'/; may concern:

Be itknown thatI, JOHN W. DURR, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Mangles, of which the following is a specification.

My invention relates toimprovements in mangles, and it more particularly seeks to provide an attachment to be used in connection with an ordinary type of mangle; and the invention primarily has for its object to provide means to prevent the adhesion of the goods to the presser-rollers.

In its generic nature the invention comprehends a series of endless cord belts which take around the presser-roller and pass in the direction of the circumference of the main drum to near the first apron-roller.

With this and other objects in view, which will be hereinafter apparent, the invention consists in certain novel combination and ar rangement of parts, all of which will be first described in detail and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which 1 Figure 1 is a vertical longitudinal section of the mangle with my invention applied. Fig. 2 is an enlarged diagrammatic view illustrating the arrangement of thepresser-rollers, the drum, and the apron-rollers with my invention applied. Fig. 3 is a top plan view of the main drum and the lower presser-roller with my invention applied. Fig. 4 is a top plan view of the shaft with its sheaves detached. Fig. 5 is a detail view of the bracket member and its end bearing. Fig. 6 is asectional View of one of the pulleys 2', showing the manner in which the pulleys are retained in position on the rod 6.

Referring now to the accompanying drawings, in which like letters of reference indicate like parts in all the figures, A indicates the stationary heating-drum mounted on the main frame A, around a portion of which the carrying-apron Y passes, which apron Y is of the endless variety and takes around the apron-rollers U. E, and V, and which is tightened or loosened with respect to the drum A by means of a lever D and rod D and roller E, as shown.

Ndesignates the feed-box, and O the first covered roller, which cooperates with the upper steam-chest P, while the second covered roller ,R cooperates with the steam-chest S, and T designates the discharge-table, all of which is clearly shown in Fig. 1 and which may be of the ordinary construction, as they per 86 form no part ofmy present invention.

From practical experienceI have found that the goods (designated by G) when it passes be tween the second covered presser-roller R and the steam-chest S will stick to the roller R and become tangled and be wound around said roller R instead of traveling downward to the apron Y. The rollers O and R are'in practice covered with several thicknesses of cloth and press against the steam-chests P and S, and I have found that no trouble is experienced in the goods sticking to the roller 0, and it passes freely to the roller R; yet owing to the space between the roller R and the roller U the goods will stick to the roller R, and unless some means be provided to loosen the goods from the roller R. the goods will be wound upon said roller and damaged. 1 have therefore devised means to obviate this objectionable feature and to guide the goods from the roller to the apronY and prevent its sticking to the said roller R.

To the projection f of the drum A, I fasten the adjustable arms or brackets a, which have elongated apertures d bto receive the bolts 7) I), which arms are bent in the curve of the drum A and have end bearings c to receive the rod 0, which is secured to the bearings 0 by nuts 0. Mounted at suitable intervals along the rod e are a number of sheaves or pulleys around which and the roller- R takes a cord 70, which may be of the ordinary cotton cord, such as is used to tie up bundles. These pulleys i are mounted to turn loosely on the stationarily-held rod 6 and are prevented from endwise movement and are held in proper position by the pins m, which pass through apertures y in the rod e, as clearly shown in Fig.6.

As the rollers O and R are in practice wrapped with a cloth covering and r, the cord 70 will sink into the cloth, and all danger of producing a crease in the goods'is avoided.

So far as described the operation of my in vention will be best explained as follows: The

goods G is fed from the box N and the roller Fig. 1.)

O, which, rotating in the direction of the arrow 772, will carry the goods between itself and the steam-chest P toward the roller R, which roller R, rotating in the direction in dicated by the arrow n, will then carry the goods between itself and the steam-chest S to the drum A. Should the goods become stuck to the roller R, the cords I, will release it, and it then passes downward to the roller U. Upon reaching the roller U the apron Yearries it in the direction of the arrow 2 to the discharge-table T. (See ,dot-and-dash lines,

From the foregoing description, taken in connection with the accompanying drawings,

drum, said presser-roller being covered with yielding material, a rod running parallel with the axis of the heating-drum, a .plurality'of suitably-spaced sheaves rotatably mounted upon the said rod, endless cords passing over for tightening the said cords so that they become embedded in the yielding cover of the presser-roller, said means including adjustable bracket members having bearing portions to receive said rod and mounted on the main heating-drum, for the purposes specified.

2. In a mangle, a main heatingdrum, an endless apron and apron-rollers cooperating therewith; an adjacent presser-roller, a yielding cover therefor, said drum having projections, bracket members adjustably mounted on said projections and. extending toward the endless apron, said bracket members having bearing portions, a rod held in said bearing portions, sheaves mounted on said rod at suitable intervals, and endless cord belts passing over said sheaves and said adjacent presserroller, for the purposes specified.

3. In a mangle, a main heating-drum, an endless apron, cooperating therewith, an adjacent'presser-roller having yielding covering,

said drum having projections, bracket members adjustably mounted on said projections and extending toward the endless'apron in the arc of the circumference of the heating drum, said bracket members having bearing portions, a rod held in said bearing portions, sheaves loosely and rotatably mounted on said rod at suitable intervals, said sheaves being held away from the heating-drum, and 'end less belts passing over said sheaves and said adjacent presser-roller, for the purposes speci-' fied.
